I bought swift car from maruti suzuki in 14 august 2014. There was an unpleasant sound coming from tyres after 7000 kms. Both the rear tyres were facing irregular wear and tear. Firslty I told the service executive about the problem at my first service after running 10000 km. But he told me that there are few little damps in the tyre due to which the noise is coming but will stop after few kms.
Then after few days I went to maruti suzuki about the same problem but didnot get any positive response from them. At my second service after 20000 kms, I visited the maruti suzuki again but they told me there is manufacturing defect in the tyres. Then I visited the tyre company (jk tyres chd) but they told me that this is due to manufacturing defect in the swift and showed me the pictures of the other swift cars with other company's tyres (mrf, bridgestone, etc.) Suffering from the same problem of irregular wear and tear of the rear tyres. Then I visited again maruti suzuki and then they agreed to the problem of manufacturing defects in the swift car. But after so many complaints they are just agreeing to give me 50% discount if I purchase new tyres from them.
But why should I pay 50%, its manufacturing defect of maruti suzuki swift they should solve the problem permanently. Also same problem is within many cars of maruti suzuki like swift dezire, swift, etc. A very negative response from maruti suzuki company, did not expected this from such an indian trusted brand. Still in a wait of positive response to solve this problem permanently from maruti suzuki company.
